Description

  The present invention provides an outer wall material and an inner wall material for a through-hole opened for piping and wiring of equipment such as an air conditioner on a wall such as a hollow wall made of an outer wall material and an inner wall material having a space such as a wooden house. The present invention relates to a wall communication pipe that is mounted to maintain airtightness between the walls, and a wall structure that uses the wall communication pipe.

The wall of the wooden house is doubled with an interval between the outer wall material and the inner wall material, and an outer heat insulation type hollow wall structure in which the heat insulation material is arranged on the outer wall side, or an inner heat insulation type heat insulation material in which the heat insulation material is arranged on the inner wall side Many highly airtight wooden houses with a material-filled wall structure have been built as an energy-saving measure.
When installing an outdoor unit such as an air conditioner in a house with such a highly airtight wall, a through-hole with a diameter of 65 mm is usually formed in the outer wall material and the inner wall material of the wall, and the indoor unit such as an air conditioner is connected to the outdoor unit. However, if the hole is left open, there is a risk that outside air, insects, etc. may enter the space in the wall from the through hole. If outside air enters the space, the heat insulation of the wall will be impaired. In addition, a large amount of energy is wasted for air conditioning, and if insects enter, they will be damaged by the worms of wood and damage the value of the house.
In order to prevent the entry of outside air and insects into the hollow space, it has been performed to fill the opening gap of the through hole from the indoor side and the outdoor side with a synthetic resin putty and mortar. It is difficult to ensure the tightness of the wall over a long period of time because shrinkage and deterioration occur due to changes with time due to ultraviolet rays, and cracks and peeling occur, and it takes time to solidify after filling with mortar during construction. However, there is a difficulty that it is difficult to remove the hardened mortar when the air conditioner or the like is replaced.
Then, the method of the following cited reference 1 is proposed in order to solve the difficulty of the method by such filling.
That is, in the following cited reference 1, without using mortar, a spiral tube is inserted into a through hole, an elastic seal material is disposed in a gap between the spiral tube and the wall, and this elastic seal material is screwed into the spiral tube. The gap is surely closed by pressing the elastic sealing material against the wall with the fixed ring.

However, the through-holes provided to avoid damaging the aesthetics of the room due to the through-holes exposed on the wall of the room avoid damaging the load-bearing structures such as studs and streaks. When the center position on the material side is shifted, it cannot be used with the hard spiral tube described in the above cited reference 1.
Even if it tries to use the spiral tube of the above cited reference 1 for such a misaligned through hole, the spiral tube made of a hard material such as a metal such as aluminum or an engineer plastic can be almost bent. However, if it is forcibly bent, the helix formed in the helical tube is deformed and the fixing ring cannot be screwed, so that it cannot be used at all.
In addition, the method described in the cited document 1 uses a dedicated spiral tube, a fixing ring screwed into the tube, and an elastic seal material, so it is very difficult to increase the cost of materials and screw the fixing ring. There is a difficulty that requires time.
Therefore, when the center positions of both through holes of the outer wall material and the inner wall material are shifted, there is no effective method other than filling the opening with the putty or mortar having the above-mentioned difficulty.
In view of this, the present invention relates to the through-holes opened in the outer wall material and the inner wall material of the wall in order to connect the indoor unit such as an air conditioner and the outdoor unit, and the center positions of the outer wall material side and the inner wall material side of the through hole are Even if it is shifted, the airtightness in the wall is lost and the wall insulation function is prevented from deteriorating. In addition, insects enter the wall from the through hole and the wall is damaged. A simple cylindrical shape that can be easily mounted flexibly to the displacement of the through-holes on both sides so that the value of the building is not impaired, and the space in the wall can be reliably cut off from the outside space It is possible to reliably maintain the air tightness inside the wall for a long period of time using the wall communication pipe material and the wall communication pipe material, and it is also possible to easily perform installation work such as air conditioner equipment replacement work etc. It aims at providing the wall structure which can be done.

In order to solve the above problems, the wall communication tube material for a wall through hole according to the present invention can be fitted into a through hole of a wall composed of an outer wall material and an inner wall material having an interval, and the whole has flexibility and elasticity.

In addition, a flange portion is formed at the tip of the inner wall fitting portion.
Further, a cylindrical outer wall fitting portion having a length substantially equal to the thickness of the outer wall material and an outer diameter substantially equal to the diameter of the through hole is formed at the other end of the expansion / contraction portion. The length of the outer wall fitting portion combined with the length of the outer wall fitting portion is longer than the interval between the outer wall material and the inner wall material, and the outer diameter is substantially equal to the diameter of the outer wall fitting portion. Alternatively, a cylindrical insertion guide portion having a smaller diameter than that is formed.

With respect to the through-hole in which the opened center position overlaps or deviates, the wall communication pipe member is inserted until the flange portion of the inner wall fitting portion hits the edge of the inner wall member and protrudes from the outer wall member. Cut out the insertion guide part.
Furthermore, the filler is filled in the open space on the outdoor side or between the indoor side and the outdoor side generated between the wires and pipes arranged through the wall communicating pipe material.
And the space between the outer wall material and the inner wall material of the wall is blocked from the external space by the expansion / contraction part of the wall communication pipe material, and the space between the room and the outdoor space is blocked by the filler.

According to a seventh aspect of the present invention, in the wall structure of the present invention, a filler is filled in the opening gap of the flange portion on the indoor side.
The wall connecting pipe member expands and contracts the wall between the outer wall material and the inner wall material from the outside space, and fills the space on the indoor side, and the space between the room and the outside on the outdoor side by the restriction of the insertion guide portion. It is characterized by being cut off on both sides.

The invention according to claim 8 is a wall structure using the wall communication pipe material according to claim 4, wherein the center position of the outer wall material and the inner wall material having a gap are opened at substantially the same diameter. Alternatively, the insertion guide portion of the wall communication pipe member protruding outward from the outer wall member is inserted into the through hole that is displaced until the flange portion of the inner wall fitting portion contacts the rim of the inner wall member. A part of the tip is cut out as it is or leaving the base part, and a part of the tip is cut out as it is or leaving the base part protruding from the inner wall material into the room.
Further, the wires and pipes arranged through the wall communicating pipe member are squeezed by the insertion guide part and the inner wall protruding part, and the periphery thereof is bound with an adhesive tape or a wire.
The wall communicating pipe member extends and contracts between the outer wall member and the inner wall member of the wall from the outer space, and the space between the room and the outdoor is blocked on both sides of the wall.

The present invention has the above-described configuration, and the wall communication tube material can be inserted and attached to a through hole in a state where the center positions of the outer wall material side and the inner wall material side of the wall are shifted. The bellows-like portion of the expansion / contraction part is flexibly deformed to block the wall and the space between the room and the room, and the airtightness inside the wall can be maintained.
At the time of construction, since the combined length of the insertion guide portion and the inner wall fitting portion is longer than the interval between the outer wall material and the inner wall material, first, the distal end portion of the insertion guide portion is inserted into the through-hole of the inner wall material. From the inner wall of the inner wall material and the flange part of the inner wall fitting part hits the lip of the inner wall material. When it is pushed in, the bellows shape of the expansion / contraction part is restored and the outer wall fitting part is pushed out to the through hole of the outer wall material, so that it can be attached to the wall from the inside very easily.
After that, the insertion guide portion protruding from the outer wall material can be squeezed and the space around it can be blocked with an adhesive tape or wire to shut off the indoor and outdoor spaces. This insertion guide is a soft synthetic resin film that can be easily cut off with a cutter or scissors.
The stretchable portion is longer than the interval between the outer wall material and the inner wall material and can be restored, and the outer peripheral diameter is larger than the diameter of the through hole. The stretched part is subjected to bellows restoration, but the opening edges of the outer wall material and the inner wall material are brought into close contact with each other while the both ends of the stretch part are pressed with restoring force.
In the present invention, in this way, the inside of the wall can be blocked from the external space in an airtight state by the extendable part.

In the invention according to claim 2, since the insertion guide portion has a tapered shape, the center line of the through hole is formed when the tip is passed from the through hole of the inner wall material to the edge of the through hole of the outer wall material. Even if they are different, one end of the cylinder can be easily protruded from the mouth edge and can be mounted easily with its tip as a guide.
In addition, the gap generated between the wires and pipes arranged through the wall communicating pipe material is smaller than the outer wall fitting part, but the total diameter of the wires and pipes to be penetrated is the diameter of the tapered tip part. If it is smaller, the distal end portion of the insertion guide portion may be cut off with a scissors or the like for easy passage after the wall communicating pipe is attached to the through hole.

  The invention according to claim 3 is a flange formed at a boundary between the outer wall fitting portion and the insertion guide portion, and when the wall communication pipe member is inserted into the through hole, the flange is the opening of the outer wall surface of the through hole. It is possible to prevent the outer wall fitting portion from being drawn into the wall again by hitting the edge.

  According to a fourth aspect of the present invention, the insertion guide portion on the outdoor side is formed by constricting a cylindrical inner wall protrusion at the end of the inner wall fitting portion and binding the periphery thereof with an adhesive tape or a wire. Similarly, the indoor and outdoor spaces can be easily blocked from the indoor side.

  Each of the inventions according to claims 5 to 8 is a wall structure using the above-described wall communication pipe material, and the through hole in which the center positions of the outer wall material side and the inner wall material side of the wall are shifted is provided. On the other hand, by deforming and inserting the flexible wall communication tube material, the expansion and contraction part of the wall communication tube material can be freely deformed and mounted according to the positional deviation of the through holes on both sides, and the outer wall material and the inner wall material. Since both ends of the expansion and contraction part of the wall communication pipe material are in close contact with the pressed state by the restoring force at the opening edges of both through-holes, the space between the wall and the room and the outside can be surely blocked, and the airtightness in the wall can be maintained. It becomes like this.

  Furthermore, in the invention according to claim 5, the filling material is filled in the opening gap between the indoor side and the outdoor side generated between the wires and the pipes arranged through the wall communication pipe material. In addition, the inside and outside of the wall can be blocked from the external space by the expansion and contraction portion of the wall communication tube material, and the space between the room and the outside can be blocked from both sides of the wall by the filler.

  Further, in the invention described in claim 6, if the wires and pipes arranged to pass through the wall communicating pipe member are squeezed by the insertion guide portion and the periphery thereof is bound with an adhesive tape or a wire, putty is put. Without using any filler, etc., the inside and outside of the wall is cut off from the external space by the expansion / contraction part of the wall communication pipe, and the space between the room and the outside is cut off from both sides of the wall by the restriction of the insertion guide part. Is possible.

  Further, in the invention according to claim 7, by filling the opening gap of the flange portion on the indoor side with the filler, the expansion and contraction portion of the wall communication pipe material blocks the inside of the wall from the external space and fills the indoor side. On the outdoor side of the material, the space between the indoor and the outdoor can be blocked on both sides of the hollow wall by the restriction of the insertion guide portion.

  Furthermore, in the invention described in claim 8, the wires and pipes arranged through the wall communication pipe member are squeezed by the insertion guide part and the inner wall protruding part, and the periphery thereof is adhered with an adhesive tape or a wire. By bundling, without using fillers such as putty at all, the expansion and contraction part of the wall communication pipe can block the inside of the wall from the external space and block the space between the room and the outside on both sides of the hollow wall. become able to.

The present invention is a wall communication tube material for a wall through-hole and a wall structure using the wall communication tube material.
Among them, first, the form of the wall communication pipe material for the wall through hole will be described.
As shown in FIG. 1 (a), the wall communication pipe material of the present invention includes a central expansion / contraction portion 2 formed in an expandable / contractible bellows shape, and inner walls formed in a cylindrical shape at both ends 2a and 2b of the expansion / contraction portion 2. Each part of the fitting part 3 and the outer wall fitting part 5, the flange part 4 provided continuously at the tip of the inner wall fitting part 3, and the insertion guide part 6 provided continuously at the tip of the outer wall fitting part 5 is flexible. It is the structure which was integrally formed in the one continuous thick film cylinder by the synthetic resin which has the property and elasticity.

About each part which comprises this wall communication pipe material 1, as shown in FIG. 5, since it attaches to the through-holes 14 and 12 provided in the wall which consists of the outer wall material 13 and the inner wall material 11 which have the space | interval W, Since there is a relationship between the wall and the through holes 14 and 12, the relationship will be described below.
First, the expansion / contraction part 2 will be described.
The stretchable part 2 has a cylindrical bellows shape as shown in FIG. 1, and the length is longer than the interval W between the outer wall member 13 and the inner wall member 11 of the wall, as shown in FIG. When contracted (shown in FIG. 1C), the stretchable portion 2 has a length that fits within the interval W.
This part is a narrow space in the wall when it is attached to the through holes 12 and 14 provided in the outer wall member 13 and the inner wall member 11 of the wall, and the bellows shape once deformed is expanded with a restoring force. Since the edges of the through-holes of the outer wall member 13 and the inner wall member 11 are brought into close contact with each other at both ends 2a and 2b of the expansion / contraction part 2 by a restoring force, air trying to enter the wall from the through-holes is blocked and airtightness is achieved. It will be obtained.
In order to block both through holes 2a and 2b in this way, the outer peripheral diameter of the bellows-like bulging portion is set to a diameter L larger than the diameter A of the through holes 12 and 14 so as not to escape from the through holes 12 and 14. Form.
The bellows-shaped inner peripheral diameter can be used regardless of whether it is larger or smaller than the diameter A of the through-holes 14 and 12, but an indoor unit such as an air conditioner inserted through the through-holes 14 and 12 and an outdoor unit The diameter of the through holes 14 and 12 may be larger than the diameter A of the through holes 14 and 12 so that the lines and pipes connecting the two can be fully filled. However, the larger the diameter, the larger the outer diameter must be, and the more difficult it is to wear, so it is preferable that the diameter be approximately equal to the diameter A of the through holes 14 and 12.
About this bellows-like uneven | corrugated width | variety (difference of an outer periphery diameter and an outer periphery diameter), the elasticity is acquired large, so that it is large. However, since the through holes 14 and 12 must be deformed in accordance with the size of the diameter A, the width is determined to be easy to handle in consideration of the flexibility of the material and the film thickness.
The cross-sectional shape of the bellows having elasticity in the length direction of the cylinder may be any shape such as a zigzag linear shape, a curved meandering shape, or a concave-convex saddle shape, and both ends 2a and 2b have mouth edges of through holes. The intermediate portion may be formed in a spiral shape as long as it has a shape that can be brought into close contact with each other in a pressed state to obtain airtightness.
FIG. 1B shows a state in which the stretchable portion 2 is bent, and is formed in a thick-film cylindrical shape of a synthetic resin having flexibility, and the stretchable portion 2 portion can be bent very easily. It can be crushed or deformed (see the state shown in FIG. 8).

Next, the inner wall fitting portion 3 and the flange portion 4 will be described.
As shown in FIG. 5, the inner wall fitting portion 3 has a length substantially equal to the thickness B of the inner wall material 11 and an outer diameter so as to fit in the through hole 12 in a close state. It is formed in a cylindrical shape having a diameter R substantially equal to the diameter A of the through hole.
The reason why the outer diameter is set to a diameter R substantially equal to the diameter A of the through hole is that a slight gap is generated between the through hole 12 even if the outer diameter is slightly smaller than the diameter A of the through hole. However, since the edges of the through holes of the outer wall member 13 and the inner wall member 11 are brought into close contact with each other at both ends 2a and 2b of the stretchable part 2, the airtightness is not lost, and the outer diameter is larger than the diameter A of the through hole. This is because, when the diameter is slightly large, it is tightly attached to the through hole 12, but it can be attached without any problem as long as it can be deformed.
The outer diameter R may be 66 mm to 60 mm, for example, in the case of a through hole having a normal diameter of 65 mm. Of these, 63 mm is optimal for use.
This portion may be formed thicker than the stretchable portion 2, and the flexibility may be less than that of the stretchable portion 2 and harder.

The flange portion 4 connected to the inner wall fitting portion 3 at the front end of the inner wall fitting portion 3 hits the edge of the through hole 12 of the inner wall material 11 so that the inner wall fitting portion 3 is pulled into the wall. Therefore, the outer diameter of the periphery is formed to be larger than the diameter A of the through hole.
The flange portion 4 can be formed in a free plate shape such as a disc shape, a semicircular plate shape, or a polygonal plate shape. Further, the shape of the allowance for the putty in consideration of filling with the putty, or a color or shape that does not stand out on the indoor wall surface when not filling with the putty may be used.
Also, if there is a through-hole hidden behind the air conditioner on the outer periphery of the air conditioner, if a part of the flange portion 6 protrudes, cut that part with a scissors or cutter according to the situation of the installation location, etc. Since the material is a flexible film body, it can be processed freely.

Further, as shown in FIG. 4, at the outer end of the inner diameter surface of the flange portion 4 provided in the inner wall fitting portion 3, the base portion has the same diameter as the inner diameter of the flange portion 4, and the radius of the inner wall fitting portion 3 is set. A cylindrical inner wall protruding portion 7 that protrudes to the above length and has a thickness that can be flexibly deformed by the force of a finger can be integrally formed with the flange portion 4.
As shown in FIG. 17, the inner wall protruding portion 7 squeezes the wires 10 and the tubes 9 disposed so as to pass through the wall communication pipe 1, and an adhesive tape 16 or a wire (not shown) around the periphery. It can be united.
If the inner wall protruding portion 7 is too long, it is difficult to pass through the wires and pipes of the device. Therefore, it is preferable to make the inner wall protruding portion 7 as short as possible so that it can be bound with an adhesive tape or the like.

Next, the outer wall fitting portion 5 and the insertion guide portion 6 will be described.
As shown in FIG. 5, the outer wall fitting portion 5 has a length substantially equal to the thickness C of the outer wall material 13 and an outer diameter so that the outer wall fitting portion 5 is in close contact with the through hole 14 of the outer wall material 13. Is formed in a cylindrical shape having a diameter R substantially equal to the diameter A of the through hole.
FIG. 5 shows an example in which the outer wall material 13 of the wall has an outer heat insulating structure in which a multilayer structure is formed in this order from the outside to the exterior material 13a, the heat insulating material 13b, and the outer wall base material 13c.
The reason why the outer diameter of the outer wall fitting portion 5 is set to a diameter R substantially equal to the diameter A of the through hole is that between the through hole 14 when the outer diameter R is slightly smaller than the diameter A of the through hole. Although a slight gap occurs, the edges of the through-holes of the outer wall member 13 and the inner wall member 11 are brought into close contact with each other at both ends 2a and 2b of the stretchable portion 2, so that the airtightness is not lost and the outer diameter R is This is because when the diameter is slightly larger than the diameter A of the through-hole, it is tightly attached to the through-hole 14, but can be attached without any problem as long as it is in a deformable range.
This part may be formed thicker than the expansion / contraction part 2 similarly to the outer wall fitting part 5, and the flexibility may be less than the expansion / contraction part 2 and harder.

  When the leading end of the insertion guide portion 6 passes from the through hole 12 of the inner wall member 11 to the rim of the through hole 14 of the outer wall member 13, the leading end serves as a guide and smoothly guides one side of the wall communication pipe member 1. The outer wall member 13 has a function of being pulled out from the edge of the through-hole 14 of the outer wall member 13, and when the length is combined with the length of the outer wall fitting portion 5, The outer wall diameter is longer than the interval W between the outer wall member 13 and the outer peripheral diameter is substantially the same as the diameter R of the outer wall fitting portion 5 and is formed in a cylindrical body continuous with the outer wall fitting portion 5 or smaller than that. Form.

The insertion guide portion 6 can be formed in a tapered shape as shown in FIG.
In this way, when the wall communication pipe member is inserted from the through hole 12 of the inner wall member 11 toward the through hole 14 of the outer wall member 13 having a slightly different center line, the tapered tip of the through hole 12 has the taper shape. The tip is applied to the rim of the hole 14, and the through hole 14 can be penetrated smoothly. Further, when the center lines of the through holes 12 and 14 are located at greatly different positions beyond the radius, even if the tapered tip is once brought into contact with the inner surface of the outer wall member 13, it is moved slightly as it is. Thus, it can be easily inserted into the through hole 14.

In addition, a flange 8 can be formed at the boundary between the outer wall fitting portion 5 and the insertion guide portion 6 as shown in FIG. It has a function of preventing the joint portion 5 from being drawn into the wall again.
Since the flange 8 allows the through holes 12 and 14 to pass through, the flange 8 is formed to have a thickness that can be flexibly deformed by the force of a finger.
When this outer peripheral diameter is slightly larger than the diameter A of the through hole, if a slight gap is generated between the outer diameter and the through hole 14, the outer diameter is compressed and deformed and drawn into the through hole 14 of the outer wall member 13. The inner surface of 14 can be pressed with a restoring force to eliminate the gap and to be prevented from being drawn back into the wall.
When this outer peripheral diameter is made larger than the diameter A of the through hole, even if a slight gap occurs between the through hole 14 and FIG. 16 (shows a state in which the insertion guide portion 6 is cut away). As shown in FIG. 2, it is possible to prevent the outer wall fitting portion 5 from being drawn into the wall again by being caught by the mouth edge without being drawn into the through hole 14.
Even when the outer peripheral diameter is smaller than the diameter A of the through hole, a part of the flange 8 is caught by the lip of the through hole 14 and is prevented from being drawn again.

  The wall communication pipe 1 composed of the above-mentioned parts is integrally formed as a single thick-film cylindrical continuous with a synthetic resin having flexibility and elasticity, such as a polyethylene film or a rubber-like synthetic resin. The film thickness may be the same, but the film thickness may be changed.

Next, the wall structure of the wall using the wall communicating pipe material for the wall through-hole will be described by showing a construction process.
The wall structure using the above-mentioned wall communicating pipe 1 is composed of wires for connecting an indoor unit such as an air conditioner and an outdoor unit, and through holes 14 and 12 opened for passing pipes, and the inner wall material on the outer wall member 13 side of the wall. There are a state in which the center position on the 12 side is shifted (shown in FIG. 7) and a state in which the center position matches without being shifted (shown in FIG. 6). The connecting tube material 1 is inserted from the inner wall material 11 side (shown in FIG. 8), and is inserted until the flange portion 4 of the inner wall fitting portion 3 hits the edge of the through hole 12 of the inner wall material 11 (shown in FIGS. 6 and 9). The insertion guide portion 6 projecting outward from the outer wall material 13 is cut away (shown in FIG. 10), and the wires 10 and the tubes 9 (shown in FIG. 11) are arranged to pass through the wall communication tube material 1. ) Is filled with filling material 15 (shown in FIG. 12).
The wall structure itself is shown in FIGS. 5 to 12 in the case where the outer wall material 13 portion of the wall has a multi-layer structure in order of the exterior material 13a, the heat insulating material 13b, and the outer wall base material 13c from the outside (outer heat insulating structure). However, as shown in FIG. 14, a wall structure in which glass fiber or a foamed resin heat insulating material is filled between the inner wall material 11 and the outer wall material 13 may be an (inner heat insulating structure). Normally, an airtight sheet 19 is stretched on the inner wall material 11 and the outer wall material 13 for moisture prevention.
In such an internal heat insulating structure, the through holes 14 and 12 are provided by penetrating the holes in the glass fiber or foamed resin heat insulating material filled in the wall when opening, but the glass fiber or foamed resin heat insulating material is also provided. As shown in FIG. 14, if the hole of the part has the same diameter as the through holes 14, 12, the bellows-like stretchable part 2 of the wall communication tube 1 is crushed and the function of restoring the bellows-like length is impaired. Furthermore, the diameter of the hole of the glass fiber or the foamed resin heat insulating material part is cut to be larger than the outer diameter of the stretchable part 2 and expanded.
In such a wall structure, as shown in FIG. 9, even if the center positions of the through holes 14 and 12 are shifted, the flexible wall communication tube 1 is deformed and inserted into the through holes 14 and 12. The bellows-like expansion / contraction part 2 of the wall communication pipe 1 can be freely deformed and attached to correspond to the positional displacement of the through holes 14 and 12 on both sides. The interior of the wall is kept airtight by blocking the space between the inside and outside of the wall from the both sides of the wall with the filler 15 or the like. Can be held.

Next, various forms that can maintain the airtightness in the room that shuts off the mouth of the pipe of the wall communicating pipe 1 will be described in more detail.
One of them is obtained by cutting out the insertion guide portion 6 of the wall communication pipe 5 protruding outward as shown in FIG. 9 as shown in FIG. 10 and FIG.
In this embodiment, as shown in FIG. 11, the wires 10 and the tubes 9 that are disposed through the wall communication pipe 1 are different from the opening clearance of the indoor flange portion 4 as shown in FIG. A filling material 15 such as a putty is filled in the opening gap of the outer wall fitting portion 5 from which the insertion guide portion 6 has been removed.
In this structure, in addition to maintaining the air tightness in the wall by the expansion / contraction part 2, the space between the room and the outdoor is blocked from both sides of the wall by the filler 15 at the mouth of the pipe of the wall communication tube 1 from the both sides of the wall. Sex can be maintained.
In order to make the indoor side look good, when the through hole 12 is provided on the back side of the indoor unit 17 of the air conditioner so as not to be seen (shown in FIGS. 13 and 14), the indoor side through hole 12 is filled with the filler 15. Therefore, the filler 15 such as putty is filled only in the opening gap of the outer wall fitting portion 5 cut out outside the room.

In the present invention, the space between the interior and the exterior can be blocked without using the filler 15 such as putty in the opening gap of the outer wall fitting portion 5 as described above.
In that case, as shown in FIG. 13, the wall guide tube 6 of the through-holes 14 and 12 is cut away by cutting out a part of the tip with the insertion guide portion 6 of the wall communication tube 5 protruding outward as it is or leaving the base.

Also in this case, when the through-hole 12 is provided on the back side of the indoor unit 17 of the air conditioner, the flange portion 4 portion (the indoor-side through-hole 12 portion) of the indoor wall communication tube 1 is left open. Become.
In this case, before bundling the insertion guide part 6, a heat insulating material such as glass fiber may be filled in the gap between the expansion / contraction part 2 and the wires 10 and pipes 9 from the opening of the insertion guide part 6. .
When the through-hole 12 is exposed in the room, as shown in FIG. 15, the opening gap of the flange portion 4 of the indoor wall communication pipe 1 is filled with a filler 15 such as a putty. You can also

Further, as shown in FIG. 4, if the wall communication pipe 1 provided with the inner wall protrusion 7 on the flange 4 is used, as shown in FIG. 17, the wall communication pipe 1 is allowed to pass through the indoor side as well. The arranged wires 10 and tubes 9 can be squeezed and the periphery thereof can be bound with an adhesive tape 16 or a wire (not shown), etc., and combined with the binding of the insertion guide portion 6 on the outdoor side as described above, the wall The expansion / contraction part 2 of the communication tube 1 can easily block the inside of the wall from the external space and block the space between the room and the outside on both sides of the wall without using a filler 15 such as a putty.
In addition, in order to close unexpected gaps generated during construction, airtight tape, gypsum, resin putty, cement, mortar, etc. are additionally filled in, and adhesive is applied or filled to seal the hollow space and the room airtight. Sex can also be maintained.

As described above, the wall structure of the wall using the wall communicating tube 1 of the present invention is the wall outer wall material that cannot be mounted by the conventional hard plastic or metal cylindrical body by using the dedicated wall communicating tube 1. The center position of the 13 side and the inner wall material 12 side expands and contracts between the outer wall material 13 and the inner wall material 12 even with respect to the through-holes 14 and 12 that are shifted so as to avoid the structural materials such as the studs and lines. The portion 2 can be used while being curved, and the airtightness of the wall surface of the house that is about to be lost due to the opening of the through holes 14 and 12 can be reliably recovered and maintained.
In addition, when replacing an air conditioner or the like, if the filler 15 such as putty is removed, or the adhesive tape 16 or the wire is removed, the wires with the wall communication pipe 1 attached to the through holes 14 and 12 are removed. It is possible to efficiently perform the replacement operation by a simple operation of pulling out and inserting the pipes and pipes, filling of the filler 15, and binding of the adhesive tape 16 or the wire.
